Polymerization
Polymerization is a chemical course of through which monomers (small molecules) mix to kind polymers (giant molecules). Within the context of paint, polymerization refers back to the course of by which the liquid paint transforms right into a stable movie. This course of is crucial for the paint to stick to the floor and supply safety and sturdiness.
There are two foremost varieties of polymerization that happen in paint: self-polymerization and cross-linking.
Self-polymerization is a course of through which the monomers within the paint react with one another to kind a polymer chain. This kind of polymerization is usually utilized in water-based paints, because the water acts as a solvent for the monomers.
Cross-linking is a course of through which the polymer chains within the paint react with one another to kind a community of bonds. This kind of polymerization is usually utilized in oil-based paints, because the oil acts as a solvent for the monomers and a catalyst for the cross-linking response.
The speed of polymerization in paint is set by quite a few components, together with the temperature, the presence of catalysts, and the kind of paint.
The thickness of the paint movie can also be affected by the speed of polymerization. A quicker polymerization fee will end in a thicker paint movie, whereas a slower polymerization fee will end in a thinner paint movie.
The desk beneath summarizes the important thing variations between self-polymerization and cross-linking.
| Property | Self-polymerization | Cross-linking |
|---|---|---|
| Kind of response | Monomers react with one another | Polymer chains react with one another |
| Solvent | Water | Oil |
| Catalyst | Not required | Required |
| Fee of polymerization | Quicker | Slower |
| Thickness of paint movie | Thinner | Thicker |
Mixing Methods
